What is the GSTI?

The European GNSS Simulation and Testing Tools Infrastructure (GSTI) is a collaborative platform intended to support both developers of GNSS applications and equipment and providers of GNSS testing and simulation tools or testbeds.
It is an initiative launched by the European Commission , transferred to the European GNSS Service Centre (GSC) and available through the GSC web portal.

What are the services offered by the GSTI portal?

Which kind of information is available in the tools database?

Every tool available in the GSTI provides technical information (category of the tool, supported GNSS signals and frequencies, environment of use, target users) as well as access conditions (e.g. commercial purchase, renting or free access) and point of contact. Links to the tool provider’s website and datasheets are also included when available.

Who can access to the GSTI Web portal?

How can I get my tools registered in the GSTI?

You need to register yourself and your company using the GSC Helpdesk Contact Form and send a request stating that you want to include a new tool (or modify/remove if you have already available tools). In particular, fill the following fields in as:
[Market]: Other
[Subject]: <New/Modify/Remove> tool
[Question Type]: GSTI
The GSC team will provide you with a template with all the fields required for the tool and further indications, if needed. Please, note that all new information needs to be validated by GSC team before being listed among all the available tools.

What is a RF Signal Generator?

A RF GNSS Signal Generator (or simulator) is equipment recreating the RF signal(s) broadcasted by satellite(s). RF GNSS Signal Generators can simulate several type of environment faced by GNSS receivers such as multipath, urban canyon,... One of the main objectives of such tools is to enable the testing of the whole GNSS receiver’s chain in the laboratory.

What is a GNSS Field test bed?

What is a software (SW) receiver?

A software receiver is a software tool potentially supported by hardware, simulating the behaviour of a GNSS receiver. Various parameters may be included to modify GNSS signals processed, algorithms implemented, etc. GNSS signals used at the input of these tools may take different forms, and can be considered at different level of the signal processing chain. These inputs may come from various sources (software generated; real digitalized GNSS signals, real time processed thanks to hardware front-end equipment etc.).

What is a signal recorder?

What is a signal propagation simulator?

A signal propagation simulator is a tool simulating wave propagation (including reflexion, absorption, interferences…) in a modelling environment. This kind of tool is used to validate or design the algorithms used to mitigate the impact of environment at local (receiver) level.

What is a service volume simulator?

A GNSS service volume simulator is a tool or facility dedicated to the simulation and/or evaluation of performances achieved by GNSS constellations. Constellation simulation refers to satellite constellation definition and modelling. Performances to be assessed may include: service volume, DOP calculation, orbital parameters, time accuracy, ionosphere, troposphere, integrity, precision, etc.
